Code Comments
Code comments are annotations within source code that are ignored by compilers or interpreters, used to explain the purpose, logic, or functionality of code segments to human readers. They help document code for maintenance, collaboration, and debugging by providing context that isn't obvious from the code itself. Comments can be inline, block-based, or documentation-style, depending on the programming language and conventions.
Developers should use code comments to improve code readability, facilitate team collaboration, and aid in future maintenance by explaining complex algorithms, assumptions, or non-obvious behavior. They are essential in large projects, legacy systems, or when writing public APIs where clear documentation ensures others can understand and extend the code effectively. However, over-commenting or stating the obvious should be avoided to keep code clean and maintainable.
